  • Automation of Test Program Synthesis for Processor Post-silicon Validation
    • Authors: Vasudevan Madampu Suryasarman; Santosh Biswas; Aryabartta Sahu
      Abstract: Software-based self-testing (SBST) is introduced for at-speed testing of processors, which is difficult with any of the external testing techniques. Evolutionary approaches are used for the automatic synthesis of SBST programs. However, a number of hard-to-detect faults remain unidentified by these autogenerated test programs. Also, these approaches have considered fault models which have low correlation with the gate-level fault models. This paper presents a greed-based strategy, where the instruction sequences that detect the freshly identified faults are preserved throughout the evolutionary process to identify the hard-to-test faults of the processor. Subsequently, the overall coverage is also improved. A selection probability is estimated from the testability properties of the processor components and assigned to every instruction to accelerate the test synthesis. The range of performance and scalability are comprehensively evaluated on a configurable MIPS processor and a full-fledged 7-stage pipeline SPARC V8 Leon3 soft processor using behavioral fault models. The efficacy of our approach was explained by demonstrating the correlation between behavioral faults and gate-level faults of MIPS processor for the proposed scheme. Experimental results show that improved coverages of 96.32% for the MIPS processor and 95.8% for the Leon3 processor are achieved in comparison with the conventional methods, which have about 90% coverage on the average.

  • Adaptive Management Techniques for Optimized Burn-in of Safety-Critical
    • Authors: Davide Appello; Paolo Bernardi; Conrad Bugeja; Riccardo Cantoro; Giorgio Pollaccia; Marco Restifo; Federico Venini
      Abstract: The cost of Burn-In is a major concern for the testing of Automotive Systems-on-Chip (SoC). This paper highlights problematic aspects of a Burn-In flow and describes a two-layered adaptive technique that permits to optimize the stress application and strongly reduce BI test time. At the SoC level, the described methodology adaptively copes with FLASH erase time uncertainties; at the Automatic Test Equipment (ATE) level, the strategy relies on power monitors and tester intelligence. The paper reports experimental results on a SoC manufactured by STMicroelectronics; figures show an optimized usage of stress resources and demonstrates a reduction of 25% in the BI test time when using the proposed adaptive techniques.

  • NBTI and Power Reduction Using a Workload-Aware Supply Voltage Assignment
    • Authors: Yang Yu; Jie Liang; Zhiming Yang; Xiyuan Peng
      Abstract: Supply voltage assignment (SVA) can alleviate the performance aging induced by the negative bias temperature instability (NBTI) effect. However, due to the random characteristic of an actual system workload, it is difficult to estimate the aging rate and control the supply voltage reasonably. To solve this problem, we present a workload-aware SVA method (WSVA) that encapsulates the workload change into the aging estimation using an LUT-based approach. Moreover, an NBTI and leakage co-optimization strategy based on an integer linear programming (ILP) approach is proposed to obtain the optimal input vector in standby mode. Simulation experiments on multiple benchmark circuits demonstrate that the LUT-based approach can track the dynamic change of the workload online and provide an accurate aging estimate for SVA with little computation cost. Compared with the SVA method without considering the workload, the proposed aging estimation approach and the optimal input vector selection strategy in the WSVA framework can enable the CMOS circuit conserve additional power dissipation while guaranteeing the performance requirements.

  • Multiple Stuck-at Fault Testability Analysis of ROBDD Based Combinational
           Circuit Design
    • Authors: Toral Shah; Anzhela Matrosova; Masahiro Fujita; Virendra Singh
      Abstract: Automatic test pattern generation (ATPG) is the next step after synthesis in the process of chip manufacturing. The ATPG may not be successful in generating tests for all multiple stuck-at faults since the number of fault combinations is large. Hence a need arises for highly testable designs which have 100% fault efficiency under the multiple stuck-at fault(MSAF) model. In this paper we investigate the testability of ROBDD based 2×1 mux implemented combinational circuit design. We show that the ROBDD based 2×1 mux implemented circuit is fully testable under multiple stuck-at fault model. Principles of pseudoexhaustive testing and multiple stuck-at fault testing of two level AND-OR gates are applied to one sub-circuit(2×1 mux). We show that the composite test vector set derived for all 2×1 muxes is capable of detecting multiple stuck-at faults of the circuit as a whole. Algorithms to derive test set for multiple stuck-at faults are demonstrated. The multiple stuck-at fault test set is larger than the single stuck-at fault test set. We show that the multiple stuck-at fault test set can be derived from the Disjoint Sum of Product expression which allows test pattern generation at design time, eliminating the need of an ATPG after the synthesis stage.

  • Exploring System Availability During Software-Based Self-Testing of
           Multi-core CPUs
    • Authors: Michael A. Skitsas; Chrysostomos A. Nicopoulos; Maria K. Michael
      Abstract: As technology scales, the increased vulnerability of modern systems due to unreliable components becomes a major problem in the era of multi-/many-core architectures. Recently, several on-line testing techniques have been proposed, aiming towards error detection of wear-out/aging-related defects that can appear during the lifetime of a system. In this work, firstly we investigate the relation between system test latency and test-time overhead in multi-/many-core systems with shared Last-Level Cache (LLC) for periodic Software-Based Self-Testing (SBST), under different test scheduling policies. Secondly, we propose a new methodology aiming to reduce the extra overhead related to testing that is incurred as the system scales up (i.e., the number of on-chip cores increases). The investigated scheduling policies primarily vary the number of cores concurrently under test in the overall system test session. Our extensive, workload-driven dynamic exploration reveals that there is an inverse relationship between the two test measures; as the number of cores concurrently under test increases, system test latency decreases, but at the cost of significantly increased test time, which sacrifices system availability for the actual workloads. Under given system test latency constraints, which dictate the recovery time in the event of error detection, our exploration framework identifies the scheduling policy under which the overall test-time overhead is minimized and, hence, system availability is maximized. For the evaluation of the proposed techniques, multi-/many-core systems consisting of 16 and 64 cores are explored in a full-system, execution-driven simulation framework running multi-threaded PARSEC workloads.

  • A Distortion Shaping Technique to Equalize Intermodulation Distortion
           Performance of Interpolating Arbitrary Waveform Generators in Automated
           Test Equipment
    • Authors: Peter Sarson; Tomonori Yanagida; Shohei Shibuya; Kosuke Machida; Haruo Kobayashi
      Abstract: This paper demonstrates a phase switching algorithm for Interpolating Digital-to-Analog Converter (DAC) based Arbitrary Waveform Generator (AWG) that resides in Automated Test Equipment (ATE) to test semiconductor devices. This confirms a previous exercise that was made by experiment with different Intermodulation Distortion (IMD) suppression techniques and starting phase shifts to suppress IMD tones of the AWG with the interpolating DAC. We show that the poor performance of the AWG can be improved by using the phase switching algorithm over the installed base of a company’s tester platform. It is also shown that the IMD performance of AWGs across a company’s tester installed base can be equalized, and how it can be achieved using the phase switching technique. We describe how the IMD specifications of the instrument are much worse than those actually measured, and by using phase switching, better performance can be achieved than what would be possible under normal conditions. We present how this technique allows the use of a low-cost tester resource to test IMD products of such as communication application ADCs with a higher dynamic range than what was previously possible.

  • FFI4SoC: a Fine-Grained Fault Injection Framework for Assessing
           Reliability against Soft Error in SoC
    • Authors: Xiaozhi Du; Dongyang Luo; Kailun Shi; Chaohui He; Shuhuan Liu
      Abstract: Recently, system-on-chips (SoCs) are increasingly employed in reliable applications for their high-performance and high-densities. Moreover, the structure shrinking of SoC leads to its proneness to radiation-induced soft errors. This paper presents a fine-grained fault injection framework for SoC (FFI4SoC) to assess the reliability of SoC against soft errors. FFI4SoC facilitates fault injection for SoC by defining the primary components and rules that are required by fine-grained fault injection. Furthermore, based on FFI4SoC, we develop a fine-grained fault injection tool named SSIFFI for bare-metal MicroZed. The design of SSIFFI is presented in order to illustrate the application of FFI4SoC. Finally, SSIFFI is engaged in simulated fault injection experiments to explore the cause of single event functional interrupts (SEFIs) and to validate functional properties of FFI4SoC. The experimental results disclose detailed reasons for SEFI and prove that FFI4SoC can be employed to assess reliability of SoC well with the merit of fine-grained injection.

  • A Diagnostics Method for Analog Circuits Based on Improved Kernel Entropy
           Component Analysis
    • Authors: Zhijie Yuan; Yigang He; Lifen Yuan; Zhen Cheng
      Pages: 697 - 707
      Abstract: Kernel entropy component analysis (KECA) is a new method to extract features and perform dimension reduction by preserving most of Renyi entropy. However,it appears to have deficiencies. The entropy estimation in KECA may be not the most accurate and it is sensitive to a single kernel radius. This paper proposes a multiplicative bias correction method of the entropy estimation. According to the analysis of the relation of statistics in the kernel feature space,we introduces two kernel radii to make KECA less sensitive to the kernel radius.A method for fault diagnosis of analog circuits based on the combination of improved KECA and extreme learning machine (ELM) is presented.Through wavelet decomposition of sampled signals,features are extracted, following improved KECA for feature dimension reduction.Next the fault patterns are classified by ELM.Case studies on two analog circuits demonstrating our diagnostics method are presented.

  • A Low-cost Dithering Method for Improving ADC Linearity Test Applied in
           uSMILE Algorithm
    • Authors: Yan Duan; Tao Chen; Degang Chen
      Pages: 709 - 720
      Abstract: Analog-to-digital converters (ADCs) are an important component in electronics design. One of the difficulties being faced is to be able to accurately and cost-effectively test the continually higher performance of ADCs under budget constraints. Test time for static linearity is a major portion of the total test cost. Our group proposed an ultrafast segmented model identification of linearity error (uSMILE) algorithm for estimating linearity, which reduces test time dramatically compared to the conventional method. However, this algorithm produces large estimation errors in low resolution ADCs (10-12 bits) when the input is a ramp signal, for which the quantization noise of ADC becomes a dominant part in the total noise. In this study, we propose three types of distribution dithering methods added to the ramp input signal to reduce the estimation error when uSMILE was applied to low resolution ADCs. Fixed pattern was proved to be the most efficient and cost-effective method by comparing with the Gaussian, uniform, and fixed-pattern distributions. The simulation results indicate that the estimation error can be significantly reduced in a 12-bit SAR ADC with effective dithering. Furthermore, a hardware evaluation board with commercial ADC products was used to validate the effectiveness of the fixed-pattern dithering methods, and our measurement shows the INL estimation error can be reduced to less than 0.1 LSB. Such dithering method relaxes the input requirement of uSMILE algorithm which dramatically reduces the test setup cost.

  • A Reliability-Aware Methodology to Isolate Timing-Critical Paths under
    • Authors: Ankush Srivastava; Virendra Singh; Adit D. Singh; Kewal K. Saluja
      Pages: 721 - 739
      Abstract: Temporal unreliability due to aging, such as Negative-Bias Temperature Instability (NBTI) and Hot Carrier Injection (HCI) effects etc., in the CMOS circuits may not appear just after the chip production, instead it becomes apparent when it is used under certain workload and environmental conditions over time. Identifying aged paths that may become critical to circuit performance, is a real challenge for many researchers and reliability engineers. In this work, firstly we identify a set of parameters that impact the circuit performance under aging and use them in the proposed algorithm which is substantially faster than commercially available SPICE simulator with an approx 94% accuracy in estimating path delays. Secondly, we explore the possibility of using the proposed methodology, instead of using time expensive SPICE and pessimistic static timing analysis (STA), to identify a set of speed-limiting paths under aging. Experimental results demonstrate the effectiveness of the proposed algorithm and the associated methodology in comparison to SPICE simulated results.

  • Study on Magnetic Probe Calibration in Near-field Measurement System for
           EMI Application
    • Authors: Gengxin Tian; Jun Li; Xiaofang Liu; Lixi Wan; Liqiang Cao
      Pages: 741 - 750
      Abstract: Near-field measurement, as an efficient method for studying the electromagnetic interference (EMI) problem, is becoming increasingly important. The calibration of the near-field probe is a critical part in the measurement procedure. This paper presents a fast and effective calibration method of magnetic probe. The factors that influence the calibration method is analyzed and discussed. Two kinds of calibration structures are designed and fabricated to determine the probe factor (PF) of two magnetic probes, which are horizontal magnetic field probe and vertical magnetic field probe, respectively. Moreover, PF is obtained through comparing the measurement data with the simulation data of the same calibration structure. Another sample is designed and fabricated to verify the obtained PF and the calibration method. The measurement results match simulation results well with the relative errors at the “large signal region” less than 20%, which indicates a good accuracy of the calibration method.

      Abstract: The ever increasing size and complexity of today’s Very-Large-Scale-Integration (VLSI) designs requires a thorough investigation of new approaches for the generation of test patterns for both test and diagnosis of faults. SAT-based automatic test pattern generation (ATPG) is one of the most popular methods, where, in contrast to classical structural ATPG methods, first a mathematical representation of the problem in form of a Boolean formula is generated, which is then evaluated by a specialized solver. If the considered fault is testable, the solver will return a satisfying assignment, from which a test pattern can be extracted; otherwise no such assignment can exist. In order to speed up test pattern generation, the concept of D-chains was introduced by several researchers. Thereby supplementary clauses are added to the Boolean formula, reducing the search space and guiding the solver toward the solution. In the past, different variants of D-chains have been developed, such as the backward D-chain or the indirect D-chain. In this work we perform a thorough analysis and evaluation of the D-chain variants for test pattern generation and also analyze the impact of different D-chain encodings on diagnostic test pattern generation. Our experimental results show that depending on the incorporated D-chain the runtime can be reduced tremendously.

      Pages: 769 - 773
      Abstract: In this paper, a 65 nm MOSFET 3D structure is built based on Technology Computer Aided Design (TCAD) 3D device simulation software, and the single-event transient (SET) effect in 65 nm CMOS inverter is analyzed using TCAD-HSPICE mixed-mode simulation based on heavy ion model. The formation and function of the PN junction diffusion capacitance in the Metal-Oxide-Semiconductor (MOS) device are discussed by analyzing the drain and substrate voltage characteristics of the device under the SET effect. Then the sub-circuit structure of this device for SET is established, and the mechanism of the diffusion capacitance of PN junction during the heavy ion action process is verified comparing with the results of sub-circuit HSPICE simulation results and the TCAD-HSPICE simulation results. Finally, A sub-circuit model is provided, to support circuit-level simulation of single-event effects.

  • A Low Power Online Test Method for FPGA Single Solder Joint Resistance
    • Authors: Nantian Wang; Xiaoyu Ma; Xiaobin Xu; Ziqiao Rui
      Pages: 775 - 780
      Abstract: Solder joint resistance monitoring is important for electronic system prognostics and system health management. It is noted that the typical built-in self-test method of FPGA solder joint has shortcomings of large power consumption, unavailability of test pins in FPGA’s functional design and possible difficulty in location arrangement of solder joint when two pins need to be measured simultaneously. To overcome these drawbacks, an online measuring method for single solder joint resistance with the constraints of limited pin number and low power consumption is proposed. The test model of the method is introduced in detail and the power consumption is theoretically analyzed. Furthermore, corresponding experimental platform is built based on a Spartan 6 FPGA and experiments are conducted. The test results show that the method can be used for online measurement of a solder joint’s resistance of an output pin in an FPGA design with very low power consumption.
